Interesting Red Gardevoir glitch

As you know with mega hydregions ability Lernean it allows him to attack multiple times and transform. So what happens when a gardevoir with trace ends up tracing lernean? Well first off it gives the multi hit effect as expected but what was interesting was that due to damage it changed the regular gardevoir into a red mega gardevoir that will be that way until upon dying it will revert back to normal just giving this out to people to explore more of test with feel free to pop in results might be hard to do since seems so far the only method i found of this is through a mega hydregion
